KY Moonbow, a Forecast for One Very Specific Rainbow
A Cumberland Falls moonbow detector that scores each night from 0 to 100 using the moon, weather, river conditions, and the visitor's location.
Field notes
The page separates the moon-only signal from a fuller curve that adds cloud and river conditions, and it displays both across the night. Its calendar section covers the next twelve months around full moons, while the nearer forecast extends six weeks and distinguishes moon-based estimates beyond the 16-day weather horizon. The site also links its supporting sources, including Open-Meteo, the USGS gauge at Williamsburg, the National Weather Service, and Kentucky State Parks.
